8 Line & Angle Relationships

Edit 0 2 …
Unit 9 Line and Angle Relationships
Students will be able to:
  • Use informal arguments to establish facts about the angle sum and exterior angle of triangles
  • Use informal arguments to establish facts about the angles created when parallel lines are cut by a transversal
  • Use slope to identify parallel and perpendicular lines

 10.3
 Angle Relationships Formed by 2 Lines Intersected by a Transversal (Problem 3 isn’t great. Give them the drawings and transparencies for #5.)

 10.4
 Slopes of Parallel & Perpendicular Lines (parallel lines used to show ‘no solution’ to systems)
